C.5.8. Linux::Process Counts by State

The Linux::Process Counts by State probe identiﬁes the number of processes in the following states:

• Blocked — One that has been switched to the waiting queue and the state of the process has been

switched to the waiting state.

• Defunct — One that has terminated (either because it has been killed by a signal or because it has

called exit()) and whose parent process has not yet received notiﬁcation of its termination by

executing (some form of) the wait() system call.

• Stopped — One that has been stopped before its execution could be executed.

• Sleeping — One that has been removed from memory by the medium-term scheduler to reduce the

degree of multiprogramming. It is later reintroduced into memory and execution resumes where it

left off.
